“…This method has also been successfully implemented in woody plants. Using seedlings as explants, composite plants have been generated from a wide range of woody plants, including Camellia sinensis ( Alagarsamy et al., 2018 ), Discaria trinervis ( Imanishi et al., 2011 ), Persea americana ( Prabhu et al., 2017 ), Taxus baccata ( He et al., 2022 ), Carica papaya ( Hoang et al., 2022 ), Citrus ( Ma et al., 2022 ), Ailanthus altissima ( Cao et al., 2023 ), Aralia elata ( Cao et al., 2023 ), Clerodendrum chinense ( Cao et al., 2023 ), Caragana sinica ( Diouf et al., 1995 ), and Malus pumila ( Pawlicki-Jullian et al., 2002 ; Yamashita et al., 2004 ) ( Table 1 ). Although seedlings can be used as explants for woody plants, the genetic heterozygosity of these plants requires the use of a sufficient number of transformed lines to ensure the accuracy of experimental results, particularly in studies of stress resistance and other biological phenomena.…”
